2.6 Operator Programming Errors
Settings for N.C. and N.O. input for the following functions were selected
simultaneously:
• External Search Command 1 and External Search Command 2 (61 vs. 62)
• Fast Stop N.O. and Fast Stop N.C. (15 vs. 17)
• KEB for Momentary Power Loss and High Slip Braking
(65, 66 vs. 68)
• Motor Switch Command and Accel/Decel Time 2 (16 vs. 1A)
• FWD Run Command (or REV) and FWD/REV Run Command (2-wire)
(40, 41 vs. 42, 43)
• External DB Command and Drive Enable (60 vs. 6A)
• Motor Switch Command and Up 2/Down 2 Command (16 vs. 75, 76)
One of the following settings was entered while H1-oo = 2 (External
Reference 1/2):
• b1-15 = 4 (Pulse Train Input) but the pulse train input selection is not set
for the frequency reference (H6-01 > 0)
• b1-15 or b1-16 set to 3 but no option card is connected
• Although b1-15 = 1 (Analog Input) and H3-02 or H3-10 are set to 0
(Frequency Bias)
H2-oo is set to 38 (Drive Enabled) and H1-oo is not set to 6A (Drive
Enable).
H1-oo is set to 7E (Direction Detection) and H6-01 is not set to 3 (for V/f
Control with PG using terminal RP as speed feedback input).
Digital Operator Display
The drive, control board, or terminal board have been replaced and the
parameter settings between the control board and the terminal board no
longer match.
Digital Operator Display
Frequency reference is assigned to an option card (b1-01 = 3) and an input
option card is not connected to the drive.
The Run command is assigned to an option card (b1-02 = 3) and an input
option card is not connected to the drive.
Frequency reference is assigned to the pulse train input (b1-01 = 4) and
terminal RP is not set for frequency reference input (H6-01 > 0)
Although the digital card input is set for BCD special for a 5-digit input
(F3-01 = 6), the data length is set for 8-bit or 12-bit (F3-03 = 0, 1).
The following values have been set while an AI-A3 option card is installed:
• The source of frequency reference setting is assigned to an option card
(b1-01 = 3).
• The action for the analog card is set for separate terminal input
(F2-01 = 0).
Digital Operator Display
A control mode has been selected that requires a PG option card to be
installed, but no PG encoder is installed (A1-02 = 1, 3).

YASKAWA ELECTRIC SIEP YEAHHP 01B YASKAWA AC Drive – A1000 HHP Programming Manual
• Check if contradictory settings have simultaneously been assigned to the
multi-function input terminals.
• Correct setting errors.
Correct the settings for the multi-function input terminal parameters.
Error Name
Initialization Required
Possible Solutions
Set A1-03 to 555o to load the parameter settings stored in the terminal board
to the drive. Initialize parameters after drive replacement by setting A1-03
to 1110 or 2220.
Error Name
Run Command/Frequency Reference Source Selection Error
Possible Solutions
Reconnect the input option card to the drive.
Set H6-01 to 0.
Set F3-03 to 2 to set the input data for 16-bit.
Properly set parameters.
Error Name
Control Method Selection Error
Correct the setting for the control method.
Possible Solutions
• Connect a PG option card.
• Correct the value set to A1-02.
Error Name
Multi-Function Analog Input Selection Error
A contradictory setting is assigned to multi-function analog inputs H3-02,
H3-06, or H3-10 and PID functions conflict.
